Hey there!
As simple as this is i gotta ask this now...is it possible to make the Carousel responsive to not only browser-width but also browser-height?...it is so simple but it seems to be impossible right?
Thanks a lot!

Yes it is not possible right now :/
I just got this feature implemented when you have fullscreen slider activated and check "lay options" -> "fullscreen slider addon" -> "Give elements a max-width and max-height and center them"
